api/v1/topictree math section bloat #135

Closed kdadmin closed 5 years ago

kdadmin commented 5 years ago

In 2012, there were 1618 unique videos in the math section. Some of those videos were used in multiple math topics for a total of 1807 video references (189 duplicates).

It gave the appearance of a structured math class from basic to advanced.

Today, including the kMAP section, there are 4605 unique videos and 19,149 video references (14,544 duplicates).

Basically the topictree repeats the math section 4X under various math topic structures and labels.

I'm curious what the reason is for the duplication, and if the api will ever get back to a sort of structured math class?

Thanks

Update/correction (cannot edit original post):

Bloat is probably the wrong way to describe it.

I can see the api supports custom curriculum for various organizations, i.e. ICSE, Illustrative Mathematics, Eureka Math/EngageNY, etc.

My difficulty is sorting from the 80 child topics a single KA curriculum which a student could work through from start to finish. Being a non-educator, I'm not qualified to do that.

Perhaps it's just a matter of topic organization?

I don't think we have a supported way to do this right now other than looking at the list of topics shown on the website. (The question of "topics a single student could work through" is a surprisingly complex one when you start to consider content aligned to different sets of standards.) You can probably get reasonably close by looking only at topics that have "listed: true", but the best way may be to just look for the topics shown in the menu on khanacademy.org.
